Fix summarize review prompt version for DAP Duo Code Review

What does this MR do and why?

This MR is the counterpart for refactor: add summarize review prompts with duo... (gitlab-org/modelops/applied-ml/code-suggestions/ai-assist!4256 - merged).

During gitlab-org/modelops/applied-ml/code-suggestions/ai-assist#1802 (closed) investigation, we realized the DAP Duo Code Review prompts were using the old review_merge_request unit primitive used in Classic Duo Code Review.

gitlab-org/modelops/applied-ml/code-suggestions/ai-assist!4253 (merged) fixed the issue for the main review_merge_request prompt but the summarize_review prompt had the same issue.

How to set up and validate locally

1. Enable Feature.enable(:ai_catalog_flows) feature flag

2. Seed foundational flows if not already seeded: ::Gitlab::Seeder::FoundationalFlows.seed

3. Create a new group and enable GitLab Duo for it

4. Create a project under that group

5. Enable foundational flows (you can try enabling Duo Code Review for the test) under Settings > General > GitLab Duo features: E.g. http://gdk.test:3000/groups/gitlab-duo/-/edit

   

6. Create a MR under that project and add @GitLabDuo to the reviewers list

7. Check gitlab-ai-gateway logs and make sure the 3.0.0 prompt version is being used for summarize_review
